Configure and Customize Dell PowerFlex v3.6.x

Mount PowerFlex

The exposed PowerFlex volumes are connected to the servers via the network. To configure mounting options of PowerFlex devices, follow the instructions for your specific Linux-based operating system, below.

1. Determine the /dev/disk/by-id correlation to /dev/sciniX:

   ls -l /dev/disk/by-id/ |grep scini

   Output similar to the following appears:

   lrwxrwxrwx 1 root root 12 Mar 2 05:35 emc-vol-7ec27ef55b8f2108-85a0f0330000000a -> ../../scinia
   lrwxrwxrwx 1 root root 12 Mar 2 05:35 emc-vol-7ec27ef55b8f2108-85a0f03200000009 -> ../../scinib
   lrwxrwxrwx 1 root root 12 Mar 2 05:35 emc-vol-7ec27ef55b8f2108-85a0f02c00000003 -> ../../scinic

2. Run the mount command:

   mount /dev/disk/by-id/<EMC-vol-id>

   Example:

   mount /dev/disk/by-id/emc-vol-7ec27ef55b8f2108-85a0f0330000000a /mnt_scinia

3. To make the mount command persistent, edit the /etc/fstab file according to the instructions for your operating system:
   • RHEL 6.x:
     1. In /etc/fstab, use a text editor to add the PowerFlex mount lines:

        /dev/disk/by-id/emc-vol-7ec27ef55b8f2108-85a0f0330000000a /mnt_scinia ext4 defaults 0 0

     2. In /etc/rc.local, use a text editor to add the mount commands:

        mount /mnt_scinia

   • RHEL 7.x:

     In /etc/fstab, use a text editor to add _netdev to the PowerFlex mount lines.

     Example:

     /dev/disk/by-id/emc-vol-7ec27ef55b8f2108-85a0f0330000000a /mnt_scinia ext4 defaults,_netdev 0 0

     Ensure that you comply with the netdev and syntax rules for your file system, as described in the man page.

   • SLES:

     In /etc/fstab, use a text editor to add nofail to the VxFlex Ready Node mount lines.

     Example:

     /dev/disk/by-id/emc-vol-7ec27ef55b8f2108-85a0f0330000000a /mnt_scinia ext3 nofail 0 0

     Ensure that you comply with the nofail and syntax rules for your file system, as described in the man page.
